It all started with the battery powered calculator, kids using it no longer had to know the rules of math. Then when we progressed to laptop personal computers with auto spell, so kids with it no longer had to remember the exact spelling of words. With the advent of portable GPS devices, kids using this device no longer had to be able to read maps.
Now a dead device battery means things not adding up, or words not spelled right, or the person not knowing where they are.
